The most dangerous hits a QB takes are in the pocket, because he's more likely to not see what's hitting him.

True, but a quarterback is more guaranteed of a taking a hit on a read-option play. Sacks and hits off pressures happen, but you tend to keep your guy clean more often than not. I just have some hesitation about using it all the time after watching a guy like RG3 come in and play some of the most exciting football ever, and leave the field a hobbled mess with a torn everything.
